If there is one thing I’ve learned in my years on this planet, it’s that the happiest and most fulfilled people I’ve known are those who devoted themselves to something bigger and more profound than merely their own self interest.
So much of what happened to me is good fortune. But I would say: Try to get a job that gives you some time; get your sleep and a little bit of food; and work as much as you can. There's so much enjoyment in doing what you love. Maybe this will open doors, and you'll find a way to do what you love.
